What a Panel Upgrade Is
A panel upgrade replaces your home’s main electrical panel with one rated for more amperage, most often a move from 100 amps to 200. The breakers, the main bus, and usually the service entrance are all replaced, giving the house more circuits and more headroom for continuous loads. It isn’t cosmetic. It’s the difference between a panel that safely carries today’s demand and one that is already running close to its limit every day.
Signs You Need an Upgrade
Most homes don’t get a panel upgrade on a whim; the house signals it. If breakers trip when a few large appliances run at once, if you lean on adapters and power strips, or if you still have a fuse box or 100-amp service, you’re a candidate. Planning an EV charger, a heat pump, or an addition almost always forces the decision, because those loads need capacity the old panel cannot spare.

How an Upgrade Is Done
The work is methodical. An electrician calculates your real and future load, then the utility de-energizes the service so the old panel can come out. The new panel, main breaker, grounding, and bonding go in, every circuit is transferred and labeled, and the utility reconnects power. A permit and an inspection close the job. Most upgrades take a single day, though utility scheduling can add time at either end of the work.

What Affects the Cost
Panel upgrade pricing turns on a handful of factors: the amperage you’re moving to, whether the meter base and service entrance also need replacing, how far the panel sits from the meter, and what your local utility and permit office require. Older homes sometimes need their grounding brought up to current code as well. We give a firm written quote with upfront pricing after an on-site assessment, never a number guessed over the phone.
100, 200, or 400 Amps?
Most homes land on 200-amp service, which comfortably runs central air, an EV charger, and electric appliances with room left over. Smaller homes with modest demand can stay at 100 or 125 amps; large homes, ADUs, or properties planning heavy electrification sometimes need 400. The right figure comes from a load calculation rather than a rule of thumb, and a good electrician sizes for where your home is heading, not only where it stands today.

Panel Upgrade FAQs
Common questions about cost, timing, and permits for a panel upgrade.
How much does it cost to upgrade an electrical panel to 200 amps?
Cost depends on the target amperage, whether the meter and service entrance need replacing, the panel’s location, and local permit and utility fees. After an on-site assessment we provide a firm written quote with upfront pricing, so the figure reflects your home rather than an average.
How long does a panel upgrade take?
Most residential upgrades finish in a single day. The main variable is utility coordination, since the disconnect and reconnect have to be scheduled with your power company, which can add time before or after the installation itself.
Do I need a permit to upgrade my panel?
Yes. A panel upgrade is permitted work that has to be inspected, and the utility must authorize the disconnect and reconnect. A licensed electrician pulls the permit and schedules the inspection as part of the project.
